Application filed March a. 1920. Serial No. 364,092,

To all whom it may concern:

Be it known that I, .FRANK J. BRUMME,

' a citizen of the United States, and a resident of Cooksville, in thecounty of McLean and State of Illinois, have invented a new and useful Improvement in Automatic Governors, of which the following is a full, clear,

and exact description,

can be adjusted at will w ile the engine is in motion, whereby the rate of speed which will be uniformly maintained can be varied. A further object of my invention is to .provide a device of the type described that is compact in form and takes up littlespace,

thereby permitting the same to be installed between the fan and the radiator in a cooling system of an internal combustion engine of ordinary construction. 7

A further bject of-. y invention is to provide a device of thetype described that is relatively simple in construction and operation and is easily. i j a v Other objec'tsand advantages will appear in the following specification, and the novel features of the invention will be particularl pointed out in the appended claims. My iifvention isillus'trated in the accompanying' drawings, forming part of this application, in which v Figure- 1 is a diagrammatic viewvof an internal combustion engine of a well known ty e showing the device applied, ig. 2 is an enlarged longitudinal sectional view of a portion of the device,

Fig. 3 is an end View of the mechanism not liable to get out of order shown in Fig. 2,

Fig. 4 is an enlarged longitiiiiinal at tional view of a portion of a of the device.

While in the" accompanying modified form have shown the device applied to aninternal combustion engine of a Ford type, it is to be I understood that the device can be used with any internal combustion engine alrd construction.

In carrying out my invention, I make use of an internal combustion engine 1, which is provided with an intake manifold 2 and a 'carbureter 3. A suitable support 4; is seof a standcured to the engine and has an enlarged top portion 5 provided. withia bore 6 in which is rigidly mounted a sleeve 7. Thesleeve 7 has acentral bore 8 in which a stub shaft 9 is slidably disposed. A pulley 10 is rotatably mounted upon the sleeve 7 and is maintained thereon by means of a'flange 11 at the end of. the sleeve 7 The fiangell, it will be no,ted,.is received within an annular recess 12 in the end of the pulley 10.

The pulley 10 is secured at 13. to a body portion 14 of a fan which has a plurality" of blades 15. It will be understood that the fan is operated by the operation of the pulley 10. i f

A housing 16 is secured to opposite blades 15 of the fan and is arranged to be rotated therewith. Lugs 17 project within the hous ing 16. A pair otallyfastened at 18 to the lugs 17. Each of L shaped rods 19- are piv' of the L-shaped rods 19 carries a weight or ball 20 at the end of one arm and has its other arm extending toward a corresponding arm of contact with a'th'rust ring 21 which is mounted upon a thrust-bearing 22. The latter is rigidly secured to an end of the shaft 9.

Anti-friction bearings 23 are provided be- -tween the thrust ring 21 and the thrust bearing 22.

The support 4: has a vertical extension 24 2 provided with a notch 26 adapted to receive the end of.a spring 25.

the other L-shaped rod and. in

The latter has its other endfastened at 27 to an arm of an L- :shaped lever 28' which is pivotally fastened at 29 to the casing of the engine 1, whereby the arm of the lever 28 is held agalnst the adjacent end of the stub shaft 9, thus holdingthe thrust member carried at the other end of the stub shaft 9 in contact with the rods 19 which carry the weights or balls 20. The other endof the L-shaped lever-"28' is pivotally fastened at 30 to one end of a vertical arm 31.

- A pin 32 projects laterally from the other 66 of the device.

end of the arm 31 and is slidably disposed Within a slot 33 provided in the carbureter 3. The pin 32 is operatively connected to the fuel control valve (not shown) within the carbureter 3.

An additional arm 34 is connected at 35 to the arm 31 and has one end slidably disposed within a suitable support 36. The

, other end of the arm 34 is pivotally connected at 37 to a lever 38 which is in turn pivoted at 39 to a 'casing of the engine or to any other suitable support. pivotally fastened at 40 to the lever 38. The arm 41 may be connected to members (not shown) leading to the drivers seat in an automobile in which the engine 1 is installed and can be operated by the driver while the engine 1 is in operation.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The pulley 10 is operated by a belt 42 which is engaged by a moving part which is preferably actuated by a member mounted upon a crankshaft associated with the engine 1.

The pulley 10 in turning, operates the fan blades 15 which in turn impart a rotary movement to the housing 16. When the housing 16 is rotated at a predetermined speed, the weights or balls 20 carried by the L-shaped rods 19 will move outwardly or away from each'other, thus exerting a pressure against the thrust ring421 and slidably moving the stub shaft 9 against the tension of the spring 25. The lever 28 will therefore be moved and the pin'32 will he slidably moved in the slot33, thus operating the valve in the carbureter and reducing the flow of fuel through the c'arbureter thereby reducing the speed of the engine. It will be obvious that a desired-speed will be uni- 1 formly maintained. The speed which will be uniformly maintained can be'varied at' will by meansof the arm 41 which is oper- 4 5. able from the drivers seat, since movement of the arm 41 will impart a corresponding movement to the arm 31 and the control valve within the carbureter will be set to permit the flow ofa larger or smaller quan- 'tity of fuel through the carburetor as it is desired to increase or lower the speed to be uniformly maintained.

Referring now to Fig. 4, it will be noted that I show a ortion of a modified form he construction of this formof device is identical with the form described with the exceptions about to be set forth and I have accordinglfy indicated corresponding parts in the two orms of the device by the same reference numerals. The sleeve 7 is I rigidly mounted within the enlarged to portion 5 of the support 4, and the pulley 10 v is rotatably mounted u on the sleeve 7 in *themanner described. he pulley 10 oper '65 ates thefan blades 15 which in turn rotate- An arm 41 is tional contact with the disk 52. A ball bearing 53 is disposed between the adjacent ends of the shafts 50 and 51. Consequently, when the weights 20 and 21 move outwardly or away from each other, the stub shaft 51 will be slidably moved within the sleeve 7 and will push the bearing53 and the shaft 50 before it, thus operating the lever and link device operatively connected with the valve in the carbureter in-the manner set forth in the description of the preferred form of the device.

It will be noted'that the shaft 51 will revolve with the housing 16 since the arms of the levers 19 are in frictional contact with the disk 52 which is carried at the end of the shaft 51.

It is obvious that a desired speed will be maintained when the device is used. One of the main advantages of the device is that the provision of the lever and link' device, operable by the driver of an automobile, permits a quick change in-speed while the engine is in operation and the automatic governor Will then maintain the speed at the rate set.
